    摘要： An optical modulator is provided which suppresses a radiation mode of a microwave generated in a connection substrate or a termination substrate from entering a signal electrode of the optical modulator and suppresses modulation properties from being degraded.
    The optical modulator includes an optical modulation element (1) having a substrate with an electro-optic effect, an optical waveguide formed on the substrate, and a modulating electrode (or a signal electrode (2)) for modulating light passing through the optical waveguide; and a connect ion substrate (4), arranged outside the substrate, for supplying the optical modulation element with a microwave signal operating the optical modulation element. A signal input terminal (22) and a signal output terminal (23) are formed on the connection substrate (20).
    A recombination suppression unit that suppresses a radiation mode (24) of the microwave signal input to the signal input terminal (22) from being recombined with the signal output terminal (23) is provided on the connection substrate.

    摘要： An optical control device is provided which can suppress crosstalk between electrodes without increasing the entire size of the device itself. The optical control device includes a substrate having an electro-optical effect, an optical waveguide formed in the substrate, and a modulation electrode modulating optical waves propagating in the optical waveguide. The modulation electrode includes at least two signal electrodes and ground electrodes arranged to interpose the signal electrodes therebetween. The optical control device further includes an electrical connection member that electrically connects the ground electrode disposed between the two signal electrodes to other ground electrodes and that is disposed to cross over part of the signal electrode.

    摘要： A method of adjusting the optical axis of an optical waveguide element which can improve a manufacturing yield of the optical waveguide element, an alignment yield between the optical waveguide element and an input waveguide means, etc. and can equalize the branch ratio in a Y-branch waveguide; and an optical waveguide element which can be made compact and also inhibited from complication in structure by using this method. The optical waveguide element (5) formed on a substrate comprises at least a linear waveguide (6) and a Y-branch waveguide (7) branched from the linear waveguide. The method of adjusting the optical axis of the optical waveguide element (5) when connecting the optical waveguide element (5) and an input waveguide means (3) for inputting a light wave into the optical waveguide element (5) is characterized in that a wide band light or two or more single-wavelength lights (light sources (1, 2)) having a different wavelength are inputted into the linear waveguide via the input waveguide means (3) and then the optical axes of the optical waveguide element (5) and input waveguide means (3) are so adjusted that light waves (10, 11) output from individual branch arms (8, 9) of the Y-branch waveguide may have nearly identical light intensity.

    摘要： It is an object of the invention to provide an optical modulator in which a connection substrate or a terminal substrate is disposed outside an optical modulation element and which can maintain at a proper voltage amplitude value a modulation signal applied to an optical modulation element. An optical modulator includes: a substrate having electro-optic effect; an optical waveguide formed on the substrate; an optical modulation element 1 having a modulation electrode (which includes a signal electrode 2) for modulating light passing through the optical waveguide; and a connection substrate 20 disposed outside the substrate to supply a modulation signal for driving the optical modulation element to the optical modulation element. In the optical modulator, a signal line for propagating the modulation signal is formed on the connection substrate, and a modulation signal monitoring output line 25 for monitoring the voltage amplitude of the modulation signal is provided right in front of an end of the signal line for supplying the modulation signal from the signal line to the optical modulation element.
